The" out;- side brake beam 18 has"connectionfthi'dugh a tie link to'a live outside'trucklevr 34" ivotallj connected at its en'd'througha clevice 35 to link- 36 pivotally connecting with the. :equalizer'hi radius bar as. Completing the brake rigging is a tiered 40 having pivotal connection "at its respective 1 ends to the-dead truck'lever 26 and the liv'etrucklever "1 28; The end of the tie rod connectin'g'witli truck" lever 26 is provide'd'with a slack adjustenl'l which can be manually operated-to vary. the point a of connection b'etweenth'e dead truck lever and the tierod-so that slack in the rigging caused PATENT 1 the rods are located above the car axles.

As an additional support for those brake beams having connection to live truck levers balance hangers are provided including supports 43 secured to the truck frame, and hangers 44 pivotally connected to the supports and rigidly fastened at their lower ends to the beams.

Actuation of the brake rigging to apply the brake shoes to the car wheels is accomplished through actuation of the main pull rod 45 having rolling connection with the radius bar 38, the bar thus being caused to move in a direction towardwthe right, Figure l. The outside truck levers 34 are accordingly actuated to apply the brake shoes associated with brake beam !8 to the car wheels and like actuation is imparted to the inside truck lever 30 through the connect-f ing tie rod 42. Movement of the truck levers 26 and 28 and their corresponding brake beams in adirection to apply-the brake shoes to the car wheels is substantially simultaneous with the actuation of the first mentioned truck levers since the pairs ofconnectedlevers are 'operativelycona nected by thepullrod32.

' For releasing the brake rigging and returning:

the operative parts to full released position the present invention provides mechanism including a release rod 4 6 supported; for reciprocating movement upon the side frame member-l by brackets 41. Telescoped over the'releaserod is a coil spring 48 havingone end in contact with the forward support: for the rod and its other end'in contact with washer 0 adjustably positioned on the rod by the pin 5|. The ends of the radius bar are supported from the frame by supporting straps 52 and by means of a connecting link 53, Figure 6. Theextreme outer ends of the radius bar have pivotal connection with the projecting end of the release rod 46 which end is bifurcated to receive the link. In Figures 7 and 8 a modified arrangement is disclosed wherein the radius bar I38 projects through an elongated slot I54 provided in the projecting end of the release rod I46. means of connecting the radius bar with the release rod provide'sufficient flexibility to allow limited lateral movement of the radius bar.v
